Proposed device comprises: tubular case (10) made from sheet metal with circular top wall (12) with inner edge (12a) that makes can top opening (A). Said top edge (12) forms convex-arc seat (S). Proposed sealer comprises also cover (20) incorporating base section (21), peripheral section (22) with circular support section (23) with its cross section representing concave arc. Circular section (24) extends radially outside of peripheral section (22) to allow seating on circular top wall (12) in closing cover (20). Circular gasket (30) is clamped by special part on closing cover (20) to form appropriate circular sealing space between cover (20) and tubular case (10). Said tubular case (10) comprises sidewall (11) furnished with top edge (11a). Circular top wall (12) is formed by circular radial rib (16) formed by recess on sidewall (11) extending inside tubular case (10), below sidewall top edge (11a).
